Adding Multiple Track Pictures at a Go

OK.

On a post I read a good time ago somebody mentioned - in a thread I think was on how Cubase 8 is doing - that you could now add multiple track pictures to several tracks at once. Different Pictures. Not talking about selecting several tracks and adding the same picture to all.
It was an offhand comment and not the topic.
I remember thinking: “Really?”. I tried it and it worked! Very cool.

Now I can’t remember how it was done and I can’t find the post.
Can’t find it in the manual.

I’m certain I did not Dream this.
Quit drugs years ago . . .

Anybody?

Hit “Link” and link the tracks you want to have the same picture. It’ll work in one go!
